' METAL SHEETING.

Application filed. April 5, 1926. Serial No. 99,691. A

Our invention relates to metal sheeting. It hasto do with the provisionof a novel form of sheeting and a novel method of and apparatus forattachment of such sheeting to the framework of a building structure orother enclosure.

In thefirst place, we have provided a corrugated sheeting structure ofsuch cross-sectional design that a roof or other surface formedtherefrom will be capable of carrying a greater load per square footthan ordinary corrugated roofing. Furthermore, our sheeting structuremakes possible the nesting and lapping of the sheets with sufficientexactness to prevent leakage in a driving rain without the necessityofspecialfiashing or closing devices at the end laps.

Our sheeting is of such structure that it can be attached at as manypoints as is desirable with a consequent assurance of security, whilethe attaching mechanism is of such a nature that the sheeting may beremoved at any time, with expedition and without difficulty or injury tosuch sheeting. Fur-' thermore, the construction of the edges of thesheeting and of the joining structure thereof will be such that thejuncture of any two rolled sheets will be stronger than the corrugationsbetween joints.

Our attaching mechanism is such as to avoid the use of nails or otherfastening means to pierce the metal and is, a'lso,of such nature that itcan be caused to grip and even indent the sheet so as to obviateslippage of the fastening means and of the sheeting as well.

Furthermore, we have provided a fastening means which obviates thenecessity of bolts and nuts and which can be causedto grip and hold thesheeting structure in position with a minimum expenditure of labor.

In addition, our fastening means may be of such nature that it can becausedto secure the sheeting structure to the building structure merelyby lapping a portion of the fastening means around a portion of thebuilding structure.

Our invention is illustrated in the accompanying drawings whereinsimilar reference numerals designate corresponding parts in theseveralfigures and wherein:

' Figure 1 is an end elevation showing one method of assembling andsecuring the sheets and cap pieces together. I I

Figure 2 is an end elevation showing a modified cap piece and itsvrelation to the sheets to prevent leakage of water by capillaryattraction between the contacting metallic surfaces. 7

Figure 3 is an end elevation of a'further modified design and showingone manner of attaching the assembled sheets to a back- Figures 9, 10and 11 are views showing difierent methods and devices for attaching'the assembled sheets to a backing and Figure 12 is a side elevation ofthe device shown in Figure 11. y

In the drawings, it will be seen that our invention comprises'thesheetsl which are,

preferably, formed with longitudinal corrugations 2 intermediate theiropposite sides.

The sheets 1 may, of course, be of any desired size but a rectangular.shape is preferred. The sheets 1 may be bent'upwai-dly and thendownwardly, as shown in the figures, to form the substantially angularportions 3 and the depending portions 4: which are adapted for a purposehereafter described. The edge portions of the sheets may be bent into agreat many shapes and two are illustrated in Figures 1- and but withoutany intention of limiting the invention thereto. 1

Adapted to interfit between the spaced edges of the separate sheets areprovided the erably, far enough toward the sheets 1 to prevent leakageof water and, if desired, a space 8, such as is shown'in Figures 2 and 3may be formed by suitably designing the sheet edges and legs of the cappieces. The purpose of this space is to break the capillary pathsbetween the metallic surfaces and, so, prevent leakage of water. Theportions 1 and web 9, preferably, terminate in the common plane of theconnected sheets to assist in supporting the load upon the sheetsurfaces.

The portions 1 of the sheetsl are provided with rows of elongated(Figure 6) or circular (Figure '7) openings and the webs 9 of the cappieces are provided with similar openings so that some fastening meansmay be inserted through,registering openings in the three members. Theholes in the portions 1 of the sheets 1 and the holes in the web 9 ofthe cap piece are, preferably, so arranged and of such size thatregistering openings can always be found and the sheeting and cap piecesbe assembled without difficulty. For holding the sheets and cap piecestogether, pieces of wire 10 bent, somewhat, in the manner illustrated inFigures 1 and 2, are preferred and some of these may be provided withextensions 11 which may be bent around parts of the backing, as shown at12 in Figure 9, to securely hold the assembled sheeting in properposition.

Figure 10 illustrates a modified device for use in place of the wire 11heretofore described. This consists of a hook 13 which may be hookedinto the openings in the sheets 1 and webt) of the cap piece, and theextensions 14, which may be wrapped around any convenientpart of thebackin illustrated at 15 in Figure 9.

Figures 11 and 12 show different views of a further modified devicewhich .may be used inplace of those heretofore described for holding thesheets in proper position with reference to the building framework orother backing. This device comprises the bifurcated portion 16 and itslegs 17 and 18 areoppositely sprung so that it may be straddled over theportions 4: of the sheets on opposite sides of the web 9 and twisteduntil the teeth 19 engage in holes, when the extensions 20 may besecured to some part of .the backing.

When necessary, the separate sheets may be placed end-to-endandoverlapped by cut ting away a part of the web 9, as shown at 21 inFigure 8. This cutting away of the web makes possible overlapping of theleg portions 6 and '7 to secure a water and weather-tight joint. Asurface of any size may be covered by securing together the sides of thespaced parallel sheets and overlapping the end-to-end sheets in themanner just described. i

It will thus be obvious that this invention all as provides a practicalmethod of securing sheets together and of securing the assembled sheetsto the framework of a portable building or other structure and that there.- sulting assembly is positive and substantial, although readilydisassembled without damaging, when necessary.

It will, furthermore, be apparent that we have provided a sheetingstructure wnich may be manufactured from a sheet of irregular contouras, for instance, a trapezoidal form, without necessity for squaresheeting. For. instance, if one edge of a sheet is out of parallelismwith another edge of the sheet, the sheet may, nevertheless, becompletely flanged, inasmuch as this will merely result in one of theedge flanges 1 extending down a greaterlength at one end than at theother .the opposite edge of the sheet would then be punched, gauging thesheet in the machine from the same edge as was used in punching'thefirst row of holes. Ifdesired, the gauges of the machine could be soarranged and set up that the second row of holes would be punched withreference to the first row of holes. In other words, the gauges would beconstructed so that they would engage with the holes in the first row.Either one of these methods would insure that the second row of holeswould be parallel to the first row of holes irrespective of the edges ofthe sheet. The sheet is then passed onto the forming dies. In placingsheet in the forming dies, it would be held by a gauge which wouldengage with the punched holes, insuring that the corrugations of thesheet would be made in true and proper relation to the row of holes,irrespective of the edges of the sheet.

Another point of considerable importance is that the sheeting structureis of such a form that it can be made fromfhot dipped galvanizedsheeting without injury to the galvanized surfaces. It is well knownthat these galvanized sheetings have a tendency to crack or scale offwhen bent around too small a radius. In addition, it will be noted thatthese joints of our structure which are bent at the most acute angle areprotected from the weather, thus causing an additional safeguard againstthe elements.

Furthermore, it will be noted that we have provided a means whereby apiece of fiexi ble wire can be converted into a fastening device merelyby the insertion through apertures in the sheeting and cap structuresand by bending of the wire to such a form that it prevents slippage ofthese parts with relation to each other and with relation to thebuilding structure. Thus, no application of nuts to threads is necessaryand the use of slots instead of holes renders the application of thisfastening device extremely simple, al-. though the use of enlarged holeswould accomplish substantially the same result and, furthermore, iswithin the spirit of our invention.

Having thus described our we claim is:

1. A sheeting comprising spaced parallel sheets having perforateddepending edge flanges, a cap piece having a web adapted to fit betweensaid flanges and having openings adapted to register in a variety ofpositions with the openings in said sheet edge flanges.

2. A sheeting comprising sheets having spaced depending edge portionsand cap pieces secured between said edge portions by depending webmembers said depending side invention, what portions and said webmembers terminating in substantially the common planes of said sheets. I

3. A sheeting comprising spaced parallel sheets having their adjacentedges turned upwardly and then downwardly, caps p0sitioned between saiddownturned portions and having parts overlapping said upturned portionsand means for securing said caps and sheets together, said means havingextending portions designed to be wrapped around a backing.

a. A sheeting comprising spaced parallel sheets having perforateddepending edge flanges,cap pieces adapted to be secured between saidsheets and having holes adapted to register with the perforations insaid edge flanges and means for securing said cap pieces and sheetstogether, said means having an extending portion for wrapping around abacking.

In testimony whereof we hereby aflix our signatures.
